23 and 6 is a carriage running upon anti-fric.

frame. or carrier 9 which is pivotally con-` nected at 9a with thecarriage 6 in front of` the platenso that the platen 8 may have alimited up and down inotion with the platen frame, it being understoodthat the usual detent (not shown) is carried by the platen frame andcooperates with the platen or with the I'line spacing wheel thereof. Theframe l) is p vided with an ,anti-friction roller 10 which runs upon ashift rail or bar 11, carried by arins 11u from a rock shaft 12 which isjournaledin hangers from the top plate 3 and is rocked by a link 13,bell-lever 14, link 15 and a key lever 16, said parts being pivotallyconnected. The drop 4 in the frame 3 provides an unobstructed space forthe lower..-parts of the platen-carrier 9 to afford a travel thereofwith the carriage, beyond the sides of the machine frame.

The two'series of segnientally arranged upwardly and rearwardly strikingtype bars 17 are supported at their pivotal en'ds by two type barsegments 18 of different radii and which are rigidly connected to thetop plate 3 and niay be east as one part or connected together in anysuitable nianner, but whether cast in oii'e 'piece or connected by anysuitable means may be regarded as two segments. ln the `disposition ofthe parts illustrated in thegdrawing, these segments 18 are arrangedvertically one below or outside of the other with relation to theprinting point,'a`n l each seginent has its ends at about the level ofthe bottoni of the platen 8 and these ends are ear.- ried backward in astep-like manner, as indicated at 19, to receive the hangersmfor thetypevbars at -the sides of the systoiii. This arraiigeinentlol the typebar segments perniits the platen carrier 9 to be pivotally connectedwith the carriage 6 at a point in front of the platen 8 and simplifiesits construction and for reasons which will hereinafter appear theconstruction is rendered more efficient.

The type bars 17 shown in the drawing are mounted upon transversepivotsor Vjournals 20, whichare connected to the bars and are or ai'ins21 of.the type bar hangers, which "in such a manner that when viewed froni thelli front, the hanger has the general appearance of the letter U thecross pieces connecting the lugs, ears or arnis of the lower set ofhangers being lowermost, whereas the cross pieces of the hangers of theupper set are uppermost. used in connectingthe type bars and theU-shaped hangers and the hangers are connected with the segments 18 byheaded screws 22 and washers 23. The type bar hangers of one set arestaggered with relation to the hangers of the other set, whereby thetype bars that are pivoted farthest from the platen move between thosepivoted nearer the platen without, however, moving between the hangersof the uppermost set of type bars. The ty e bar hangers are oppositelydisposed so t at the type bar bearing portions of the hangersof one setproject t0- Ward the type bar bearing portions of the hangers of theother set in the same vertical plane and cover them, whereas the stemsof one set of hangers extend away 0r in an opposite direction from thestems of the hangers of the other set, and the pivots of the type v barsare situated in two ares arranged at different heights and intermediatethe type bar segments 18; that is to say, thel said pivots 'are at agreater distance from the printing point than one, and at a lessdistance from the printing point than the other of said segments, anarrangement that provides space for wide bearings within the limits ofthe frame of standard machines. It will be observed that, in theinstance illustrated in the drawing, the radial and segmentally arrangedtype bar hangers are mounted in two sets or series located' one directlyabove the other upon vertical faces of the segments 18 that are in thesame or substantially the same vertical plane, which is the preferredarrangement, and that the construction is such as to afford a radialadjustment of each hanger and also a lateral adjustment thereof aroundthe associate screw 22 therefor.

While the front faces of the segments 18 and the eoperating securingfaces of the hangers 21 are in the same' or substantially the samevertical plane it will be observed that the pivotal points of the twosets of type bars are arranged in different relative positions on theirhangers and are situated in two parallel vertical planes and that aplane represented by the dotted line x (Fig. 2) in which the pivots ofeach fore and aft pair of type bars is situated7 is substantially midwaybetween the printing oint and a type on one of said bars when the atteris at rest, or at substantially right angles to a line extending rom oneof said types to the printing point, as indicated by the dotted line y,and that byy this arrangement the free ends of the type bars of bothsets terminate substantially in the same vertical transverse plane,except where they are stepped back at the ends of By preference,cone-bearings are i the segments. Notwithstanding this relation, thatthe pivotal centers of each fore and aft set of type bars bear one tothe other, an

individual adjustment of the hangers bothradially and laterally isafforded.

A segment 24 is'mounted in the machine in front of and below the typebar segments 18, and a single series of parallel, segmen tally arrangedbell cranks 25 of a uniform or substantially uniform size throughout theseries is pivotally connected with the segment 2A., )referably by meansof independent parallei hangers or supports 26, headed screws 27 and awasher o r covering late 28. From an inspection of Figs. 1 an 3 it willbe observed that each of the hangers 26 is formed of a single strip ofmetal doubled and folded on itself and formed with an enlargement oropening in. the stem for the passage of the stem of a screw 27 whichsecures lthe hanger in place and that the free ends of the folded stripof metal are bent outwardl to form a bifurcated ortion in which t epivoted member or t ell crank 25 is received. The bell cranks aremounted in their hangers upon" horizontal axes,.so that pivots of bellcranks are alined or extend in an arc situated in a plane that extendstransversely of the machine, andthe bell cranks areconnected with thetype bars 17 by substantiall horizontally dlsposed wire draw links 29, te pivotal connection between each type bar and its link 29 being in theplaneA of movement of the bar.

By reference to Fig. 3 it will be lobserved that the links 29 'passthrough the arms of.

the type bars 17 from the inside g that is, Said vlinks are betweentheir -respective type bars and the center of the mac ine, an arranement that contributes to com aetness and efliciency of operation.l Itwil also be seen by reference to Fig. "l that the hangers for the typebai-s and bell cranks and the pivots of thctype bars and bell cranks aresituated in'arcs, the planes of which are in parallel vertical planes,and it will be understood that .the segments 18 and the two sets of typebars occupy approximately the same angular space about the printingpoint.

The bell cranks 25 are connected with thc key levers 30 by two-partlinks 31 the members of each link being adjustably connected to shortenor lengthen thc links, the links connecting with the key levers in asingle transverse plane. rlhe key levers 30 are fulcrumcd at 30 in asingle transverse plane and the keys upon the key levers shown in thedrawings are arranged in two sets, each set containing two banks ofkeys, a front set 32 and a real' sct 33, and the bell crank 25 connectedwith the longer levers, having the front set of keys 32y are connectedwith the longer type bars 17, while the shorter key levers having therear set of keys 33 are connected with shorter type bars, thus af- Ceityhl to 'thex particularly apparentin a thin sheet inet-alferdingsubstantially uniform leverage and touch throughout the system oftype 'actio'ns,,` ,o

5,; yxfih'e;types 34 and 34EL upon each typo vahead or block 34 arearranged with their face'slkjniplanes r,which intersect in front ofthetype faces and at an obtuse angle It willbelobserved that the typefaces match a 4shiftedposition of the ilaten. o

v,areasonlof the peculiar 1beveled or incline'iiarrangement of the facesof the types,

I am enabled to place the types much closer togetherthan,heretofore andthus reduce the i., l5 amountfpfoilset or extent of cranking heretoforenecessary4 in moilnting several typ Y which approach and are at theupper ends of the segment. For example, it will ybe understoodithatif,the faces of the types were both inthe laine plane or were inclinedreversely tolthatzshown, the types would have to be widely separated inorder to avoid the ,y liahrtygof afportion of' one type printing" `wheiianother on the same bar is leavin its impression, 5 When, however, thefaces Aof theftypeson the. same bar are inclined backyavi/(ay from `eachother in the manner ,l,show/'11,!,a greater s ace is provided between,su ace yof the p aten and the type on the bar .whi his not at`the'printing point when th'ebth'er type is in printing' position, andelative'ly shorter shift of the line of obtained without liability of ppeI printing at the same blow. "`hus j ,oppose` arrangement of the typeson each tifpeblo'ckgnot only reduces cri'uniing' action., je avoidingblurring when the oiiset .Htypf'efis' printing, but Ait likewise enablesa reduce'dhshifting movement at the printing' p poi, hwithout liabilityof a part of one type printing' jilpon' the platen when the other y typon'ithesamc bar is printing'. By4 this con/struction l am able to employcomparai "tivlyfthicli vand riggid type bars whichl are i .st light,oughontthcir lengths, that'is to say, bars which at then' type ends haveno later, sidewise bends, but of course my y be used with. bars hav-''Umg suchl bends, The straight type bar avoids tl ",l'y ibility of thetype beingr deflected y orffwlriippcd out of its proper course during,lanipidl or violent inoveinentof the type bar printing position. rIlhisdefect is typebar i p 'ving a lateral bend at its free end wherethetypes are. located.1

A 4fixed sheet metalsegrnental cover plate, Idustshield 3,5(is bentandshap'cd to Aoverlie f. the platen, as indicate/dein `Fig. 2, in

es uponaban and especially those barsv erasures. It will be seen thatcach type bar has a bend, de ression or recessed portion 17* in whichthe ust shield lis received ,when the type bar is in the printingposition, so that while the pivots of the type bars are beneath theshield it nevertheless does not interfere with the movemcn t ofthe typebars to theprinting positions.

The washer or covering plate 28 shown in the drawing` is provided atitsedges wit'n lugs or ears 36 which provide spaces between them forspacing apart and' preventing motion of the hangers 26 that are seatedin. recesses formed between the lugs or ears 36on the plate 28, wherebythe hangers may be readily positioned and are prevented from turning' onthe screws 2,7. v
